SPECIFICATION forming part of Letters Patent No. 747,194, dated. December 15, 1903.

Application filed \Tune 25, 1903. $erial No. 163,084. (No model.)

T0 110% whom it may concern:

Be it known that I, KNUD K. LEROL, Jr., a citizen of the United States, residing at Amherst, in the county of Fillmore and State of Minnesota, have invented new and useful Improvements in Corn-Planters, of which the following is a specification.

My invention relates to corn-planters; and the object of the same is to construct a device of this character which will operate without the aid of a knotted cord or wire to plant corn. 1

The simple and novel construction employed by me in carrying out my invention is fully described and claimed in this specification and illustrated in the accompanying drawings, forming a part thereof, in which- Figure 1 is a plan view of my planter. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse section on the line 3 3, Fig. 1. Fig. 4 is a detail mechanism of the tongue and guide-shoe with its connected mechanism. Fig. 5 is a detail side elevation of one of the traction-wheels. Fig. 6is a detail elevation of one of the cam-disks. Fig. 7 is a detail perspective of the planting-slide-operating mechanism.

Like numerals of reference designate like parts of the different views of the drawings.

The numeral 1 designates ashaft carrying two traction-wheels 2, secured on the ends thereof. The wheels 2 are provided with rims 3, which project beyond the outer faces thereof and have radial apertures 4 formed thereon, in which steppers 5 are slidably mounted. The steppers 5 have uniform bodies and are armed with spear-heads 5 on each end, which serve to engage the ground. Connected to the steppers 5 are pitmen 6, which are also connected to cranks 7, formed on shafts 8, journaled in the wheel 2 and located near the rims thereof in a common circle. Secured to each of the crank-shafts 8 is a cogged gear-wheel 9, bearing two stop-pins 10, which are located diametrically opposite to each other and extend beyond the inner face of the wheel 9 in position to be engaged by earns 11, loosely mounted in the shaft 1 and having two cut-away portions or notches 12, formed at diametrically opposite points in the peripheries thereof. Cogged sections .13 are formed on the cams 11, adjacent to the them. To serve to hold the cams 11 against I turning on the shaft 1., but at the same time enable them to be adjusted thereon, rods 14. are provided and connect the cams 11 to oppositelyextending crank-arms 15 and 16, formed on the opposite ends of a shaft 17, journaled in side bars 17*, connected to the shaft 1. A lever 18 is provided for operating the shaft to throw the cranks 15 and 16 to rotate the cams 11 oppositelya fraction of a revolution, and thereby regulate the operation of the steppers and enable any error to be corrected. the two wheels 2 can be made to operate alternately. The lever 18 is reversed at the end of each row.

Guiding-shoes 19 are mounted on the frames ed to the shaft 17 and passes above the shaft- 1. An arm 30 is pivoted to the center to the tongue 29 and carries a guiding-shoe 31.

Lines 32 are connected to the arm 30 and to a lever 33, mounted onshafts 34, journaled in arms 35, attached to the tongue 29. By means of the lever 33 the shoe can be raised and held clear of the ground. Cranks 36 are formed on the shaft 34 and carry loops 37, which engage the shaft 1 and permit a vertical movement to the shaft 1, while the shoe 31 is in contact with the ground. Aguide member 38, pivoted to the tongue 29, holds the arm 30 against sidewise movement.

In operation my planter is hauled across the field by a team hitched to the tongue 29 and with the shoe 31 in contact with the ground. The wheels 2 will be rotated and will carry the cogged gears 9 around with By this means the steppers on them. The stop-pins 10 will engage the periphery of the cam 11 and hold the gears 9 against turning until the cogs thereon mesh with the cogged sections 13, when the pins 10' will be opposite the notches 12, and the gears 9 will be rotated one-half of a revolution. This will occur twice at every revolution of the wheels 2, and thereby complete one complete reciprocation of each of the steppers. The cogged sections 13 are so located that the steppers are driven into the ground aud then retracted as the wheels 2 turn up to be ready for the next movement. In this manner the wheels 2 are held against slipping and marks made by the steppers for the next hillof corn. In order to'regulate the position of the cam llfand thereby determine the instant the steppers shall be operated and to make those on the two wheels 2 alternate, the lever 18 is operated to throw the crank-shaft 17 to set the cams 11 and also hold them against rotation. As the shaft 2 revolves the cam-wheel 27 also revolves in unison therewith and brings the cogged sections 28 alternately into mesh with the gear 25 to operate the dropping-slide of the planters. After the machine has crossed the field in one direction it is turned around and one of the wheels 2 made to follow the old track. The lever 18 is thrown clear out at the end of each row.

I do not wish to be limited as to details of construction, as these may be modified in many details without departing from the spirit of my invention.

My invention may be applied to corn-planters of difierent makes and models.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a corn-planter, the combination of a shaft bearing two driving-wheels which run on the ground and support the machine, steppers radially mounted to slide in the rims of said wheels, gears mounted on crank-shafts journaled in said wheels and located near the peripheries thereof, stop-pins mounted in said gears, a cam-wheel loosely mounted on said first-mentioned shaft and having cogged sections thereon adjacent to notches in the periphery thereof, and means for holding said cams against turning, substantially as described.

2. In a corn-planter, the combination of a driving-wheel secured on a shaft, steppers slidingly mounted in the rim of said wheel, gears mounted on stub-shafts journaled in said wheel and bearing cranks, said gears each bearing two stop-pins located diametrically opposite each other, a cam loosely mounted on said shaft and bearing cogged sections located adjacent to notches thereon, means for holding said cam against turning on said shaft, and connectingrods pivoted to said steppers and to said gears, substantially as described.

3. In a corn-planter, the combination of a shaft bearing two driving-wheels, steppers slidiugly mounted in said wheels, two cams loosely mounted on said shaft and bearing cogged sections located adjacent to notches formed in the peripherythereof, gears mounted on said driving-wheels and located to mesh with said cogged sections as said drivingwheels revolve, mechanism connecting said gears and said steppers, a shaft journaled in the frame of the machine and bearing oppositely-extending crank-arms and a lever, and connecting-rods pivoted tosaid crank-arms and said cams, substantially as described.

4. In a corn-planter, the combination of a driving-shaft, a circular cam rigidly secured to said shaft, and having two diametrically opposed notches in the periphery thereof, oogged sections mounted on said cam adjacent to said notches, a gear located in position to be engaged by said cogged sections, two diametrically opposed stop-pins seated in said gear, and located to be engaged by the periphery of said cam to normally hold said gear against turning, and a planting mechanism mounted to be operated by said gear, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
